Ask HN: Does anyone actually use the Pomodoro technique?

I did some research and wrote about how the default 25-minute time intervals is better for breaking a procrastination habit, but longer time intervals like 50 minutes are actually needed to do deep work. Link: https://tinyurl.com/r5drje9p

I know only like one person who actually does the technique. So if you do pomodoro, how has it helped and in what ways? How do you make it stick?
